On the Benefit of Synergistic Model-Based Approach for Safety Critical Interactive System Testing

摘要

This paper claims that the design and construction of safety critical interactive systems require both a task centred approach to support efficiently operator's goals and activities and a system centred approach to increase the dependability of the system. The approach presented proposes a model-based approach integrating tasks and system models. This integration is done at the model level (in a similar way as in [13]) and at the tool level exploiting PetShop environment [3] for the system side and AMBOSS [1] for the task side. The tool level integration describes three different protocols each of them having advantages and limitations. The model-based approaches are introduced through a case study in the field of command and control systems. The application called AGENDA allows operators to define and organize work plan for satellite ground systems.
